This zero-clearance fence is an easy project that improves the performance of almost any router bit. The fence is made of 1/2-in.-thick medium-density fiberboard (MDF). Construction details are shown in the drawing.

To use this setup with a new router bit, screw a new replaceable insert into the rabbeted recess in the fence. Place the pivoting end of the fence over a dowel in the router-table top, turn on the router and swing the fence slowly through the bit to cut a reverse opening in the insert. The final placement of the fence is secured with two C-clamps. When you change the bit, you will need to install a new insert and repeat the operation.
